随着电力通信网络规模的加大,信息通信设备的集成度在逐渐提高。通信设备均属于精密电子设备,对温度湿度等环境情况非常敏感,但高集成度又导致这些设备发热严重,因此通信设备机柜的温湿度检测必不可少。传统的基于RS485总线或者CAN总线的温湿度检测设备需要单独布线,不仅施工烦琐而且通信速率较低。实验仿真和结果分析表明,利用机柜本身的以TCP/IP通信链路对机柜温湿度进行实时检测,相对于传统检测设备施工简单,通信可靠,便于大规模使用。 With the increase of the scale of power communication network, the integration of information communication equipment is gradually increasing. Communication equipment are precision electronic equipment, the temperature and humidity and other environmental conditions are very sensitive, but high integration and lead to serious heat of these devices, so the temperature and humidity detection of communication equipment cabinets is essential. Traditional RS485 bus or CAN bus based on the temperature and humidity testing equipment requires separate wiring, not only cumbersome construction and lower communication speed. Experimental simulation and result analysis show that the real-time detection of cabinet temperature and humidity using TCP / IP communication link of the cabinet itself has the advantages of simple construction, reliable communication and convenient use for large-scale compared with the traditional testing equipment.
